Hi Susan, and welcome to planDisney!
I am all too familiar with the sometimes limited MagicBand options, but I have personally succeeded in getting what I wanted with some planning.
I recommend checking the site often because the available
MagicBand options do rotate. For our last vacation, I waited three weeks prior to our arrival date and was able to find the styles and colors we desired. Waiting to purchase the MagicBands gives you time to see if your preferred styles and colors become available. This option could work as long as you are more than ten days away from your check-in date. Another option would be to check shopDisney as they sometimes have sales on the available MagicBands that you can purchase. If you take that route, you will be able to link those MagicBands to your
My Disney Experience account; the only caveat is that you do not get to personalize them. I hope this helps.
Please let us know if you have additional questions; we are here to help.
Have a magical time!
Raquel
